Over the past twenty years, poison centers across the United States have recorded over 3,600 cases of polymer fume fever, according to a Washington Post report. This condition, also known as “Teflon flu,” is a flu-like illness caused by fumes from certain nonstick coatings used in cookware. It’s named after the popular nonstick brand Teflon, but it can happen with any similar nonstick coating.
In 2023, the number of polymer fume fever cases reached an all-time high, with more than 250 people hospitalized in the US, as reported by the Daily Mail. Symptoms include fever, body aches, and chills. America’s Poison Centers noted that 2023 saw the highest number of cases in decades, possibly the most since the year 2000.
What is Polymer Fume Fever?
Polymer fume fever happens when people inhale toxic fumes from overheated polytetrafluoroethylene (PTFE), commonly known as Teflon. These fumes are released when nonstick cookware gets too hot. Although people can also be exposed to these fumes in workplaces with poor ventilation, it’s more common in households.
Symptoms of Teflon Flu
Symptoms of polymer fume fever typically appear within a few hours of exposure but can take up to 24 hours. Common symptoms are fever, feeling unwell, shortness of breath, chest tightness, and a dry cough. While these symptoms can resemble other illnesses, they often lead to underdiagnosis. Most people recover within a few days, and severe outcomes like death or permanent disability are very rare.
New Guidelines from ICMR-National Institute of Nutrition
In response to these health concerns, the ICMR-National Institute of Nutrition (NIN) in India has updated its “Dietary Guidelines for Indians.” These guidelines now include new scientific research, changing lifestyles, and evolving eating habits.
The NIN recommends using earthen cookware as the safest option. Earthen pots are eco-friendly, use less oil, and help keep the nutritional value of food intact.
The guidelines also advise being cautious with nonstick pans. The risk of harmful fumes increases if the pan’s temperature goes above 170°C. It’s essential to replace nonstick cookware if the coating is worn or damaged to avoid exposure to toxic fumes.
With the rise in polymer fume fever cases, it’s crucial to use nonstick cookware responsibly. Following guidelines like those from the NIN can help minimize risks and ensure safer cooking practices.
